New Neptune diaphragm metering pump handles difficult chemicals

Viscous or shear-sensitive fluids are no challenge for Neptune's new MP7000 pump

Neptune, part of PSG, a Dover company, has launched its new Series MP7000 mechanically actuated diaphragm metering pump, a low-flow version of the Neptune Series MP7100 metering pump.

The Series MP7000 incorporates a wide variety of design features that provide reliable and accurate dosing of a wide range of mild to aggressive chemicals, including those used in industrial and municipal water and wastewater treatment, chemical processing, and agriculture.

The pump has been engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs.

The Series MP7000 pump incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm, and reduces the potential for gearbox oil to contaminate the process.

It also features a finned gearbox that dissipates the heat created during normal operation more readily than other designs, oversized check valves that improve performance and minimise friction losses, and rugged bronze gears for quiet-running and long service life.

Additionally, the straight-through flow design of the Series MP7000 liquid end and the elimination of the contour plate results in improved flow characteristics, making the pump a suitable solution for pumping difficult chemicals such as viscous fluids, shear-sensitive fluids, and fluids with suspended solids.

Neptune Series MP7000 pumps feature capacities to 102l/h at operating pressures up to 16 bar and include a 10:1 turndown via micrometer-type knob with a high-contrast, easy-to-read scale.

Series MP7000 pumps are also available with a self-loading micrometer that prevents drift, and an optional automatic speed control with variable frequency or SCR drive.

All models include a standard 63 IEC motor adaptor.
